I noticed while i was walking on Sherman Hill last night there is a couple of snow fences that you can not reach to repair them. The one fence is near the cement plant going towards sherman hill summit direction. The other one is on the Cheyenne side of Sherman Hill summit but I can't remember the exact location. I don't know if anyone else is having this issue but I know I am. Also while walking I had to restart the game over from the Cement Factory because I was unable to get back to the tracks as it would stop me.
